UNITE HENRY H. SESSIONS, OF CHICAGO, ILLINOIS, ASSIGNOR TO THECOMPRESSED AIR MOTOR COMPANY, OF AME PLACE.

CAR CONSTRUCTION.

SPECIFICATION forming part of Letters Patent No. 665,760, dated January8, 1901.

Application filed June 12, 1899. Serial No. 720,259. (No model.)

To all whom it may concern:

Be it known that I, HENRY H. SESSIONS, a citizen of the United States,residing at Chicage, in the county of Cook and State of Illinois, haveinvented a new and usefulIniprovementin Car Construction, of which thefollowing is a specification.

My invention relates particularly to the structure of cars adapted tocarry compressed air as a motive power.

My object is to provide a construction wherein provision is made in thesubstructure of the car for storing steel tubes or holders which are tocontain the compressed motive 1 fluid, the spaces between floor-sillsand beneath said sills between the front and rear trucks being utilizedfor this purpose.

In the accompanying drawings, which represent a portion of the skeletonof a car embodying my improvements, Figure 1 is a broken view in sideelevation; Fig. 2, a broken plan section, as indicated at line 2 of Fig.1; Figs. 3, 4,'and 5, enlarged broken transverse vertical sections onthe corresponding lines of Fig. 1; Fig. 6, an enlarged broken verticaldetail taken as indicated at line 6 of Fig. 2 and showing the manner ofsecuring the bottom cross-pieces to the longitudinal floor-sills; Fig.7, an enlarged broken section at the cor- 0 responding line of Figs. 2and 8; Fig. 8., a broken section at line 8 of Fig. 7; Fig. 9, anenlarged broken section at line 9 of Fig. 2; Fig. 10, a broken sectionat line 10 of Fig. 9 and showinga meansof fixing the compressed- 5 airtubes in place; Fig. 11, an enlarged broken section at line 11 of Fig.2,and Fig. 12, a broken sectional detail view of a double-membercross-sill employed.

In the preferred construction A A represent steel channel-formlongitudinal center floor-sills; B B, similarly-described intermediatesills; C C, similarly-described side sills; D, the platform-sills, whichmay conveniently be either steel I-beams or steel channel-bars;

5 D, the draft-beams, preferably steel I-beams, arranged beneath thecenter sills A A and firmly fixed thereto; E, a series of topcrosspieces, preferably of flat or bar steel, fixed in any suitablemanner to the longitudinal sills;

E, a series of bottom cross-pieces, preferably steel channel-bars,secured to the longitudinal sills by strap-bolts a, Figs. 1 and 6,riveted to the sills and passing through perforations in the channelsand equipped beneath the same with nuts; F F, a double-membercross-sill, preferably two strong steel I-beams, located above thestirrup-plate G directly over the center wheels of the front truck; G,the end-sill stirrup-plate; H, H, H', and H clusters of horizontally-disposed tubular compressed-air holders; I, the corner uprights orposts of the car-frame; I, the door-posts; 1 a channel-form end sill; Icorner-plates joining the end sill to the outer longitudinal sills; J,vertical wooden car-posts secured to the peripheral floor-sillsbyangle-irons J; K, metallic plates secured to the angles J and to theperipheral floor-sills; K, metallic longitudinal compression members orbands riveted to the plates K and angles J; K wooden 7ocompression-blocks between the uprights J, the longer blocks beinglocated beneath the window-sills, (not shown;) L, Figs. 2 and 9,metallic hanger-plates riveted to the center and intermediatefioor-sills; M, side stirrupangles secured at their ends to the sidesills C C and riveted at intervals to downward extensions N of certainof the plates K, constituting hanger-plates corresponding in function tothe hanger-plates L, and P series of channel-form holder-supports ofsuitable lengths to fit between the hanger-plates, to which they aresecured, as by means of rivets b. The channels P have their angles cutaway for a distance at the ends and the web ends downturned to affordattachingflanges b.

The channels A A preferably extend continuously from end sill to endsill of the carbody, have their angles turned from each other, and arespaced far enough apart to admit at least one holder between them. Theintermediate sills B B are composed of sections which extend from thecross-sill member F shown to a similar member (not shown) at the rearend of the car and from the members F to the end sills of the car, theirangles being outturned, as shown. The side sills C C extend from endsill to end sill and have their angles turned inwardly, and the endsills likewise have their angles turned inwardly, and finally thecross-sills F F are in sections extending from side sills to centersills and from center sill to center sill, being secured to said sillsby short vertical angles 0.

The compressed-air holders may be put in placeduring the construction ofthe car or afterward. In any case the holder-supports are removable forinsertion or replacement of the pipes. To facilitate this, the supportsP may besec'uredfto the hanger-plates by bolts instead of rivets, thoughthe necessity for the removal of any holder would occur so rarely as torender riveting the preferred fastening means. Any suitable means may beemployed for connecting the open ends of the holders with each other andwith the motor, none being here shown. Also any suitable means forpreventing movement'of the holders in their places may be provided. Ihave shown for the purpose, Fig. 10, double end-threaded bolt-straps dd, which securely fix the holders in place by being passed throughperforations in the cross-pieces and secured by nuts. I

It is to be understood that the car is preferably symmetrical, the partnot shown being a counterpart of that shown and a similar nesting of theholders being there present.

I believe it to be new to provide a car structure wherein the spacesbetween the longitudinal floor sills, particularly from the front trucksto the rear trucks, are preserved for housing clusters of compressed-airholders, said sills being connected by bottom cross-pieces serving inplace of cross-sills and as supports for said holders. Also I believe itto be new to provide between trucks hangers depending below thefloor-sills and provided with transversely-extending holdersupports. Theholder-supports are preferably arranged in sets, as shown, and the spaceabove each set (and included space) will for the purpose of the claimsbe regarded as the space above the supports.

Changes in form, materials, and details of construction may be madewithout departure from my invention[ Hence no limitation is to beunderstood from the particular description given, except as may appearfrom the appended claims.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a car, metallic channel-bar sills having vertically-disposed webs,upwardlyprojecting metallic plates secured to the peripheral sills,upright metallic angle irons se cured to said plates, Wooden uprightsforming part of the car-frame secured to said angles, and supports forcompressed-air holders secured to the longitudinal sills, substantiallyas and for the purpose set forth.

2. In a car, the combination with the longitudinal sills thereof, ofdepending hangerplates secured to said sills between the front and reartrucks, and cross-bars secured to said hangerplates and affordingsupports for compressed-air holders, substantially as and for thepurpose set forth.

3. In a car provided with side and intermediate sills, the combinationof depending hanger-plates secured to each of said sills between thefront and rear trucks, cross-pieces extending from hanger-plate tohanger-plate, and side stirrup-pieces secured at their ends to the sidesills and between their ends to the adjacent hanger-plates,substantially as and for the purpose set forth. 4. Ina car, thecombination with the longitudinal sills thereof, of supports forcompressed-air holders at the bases of said sills and forming with thesills housings for said holders, depending hangers connected with saidsills between the front and rear trucks, and holder supports connectedwith said hangers, substantially as and for the purpose set forth.

5. In a car, peripheral metallic channel-bar sills havingvertically-disposed Webs and inturned flanges, upright metallicangle-irons secured to said sills and arranged in pairs,

each member of each pair having one outturned wing and one wing turnedtoward the other member, a metallic plate separating HENRY I-I.SESSIONS.
